In this situation, one of the better advice is to speak your mind - think deep on your own interpretation of the situation and how deep it lies and then tell him full out what you feel. The more full out the better and precise it will be for the appropriate answer.
If he is the right man for you and he really loves you and also wants to be with you for live, he should understand and respect you and your feelings. He should consider how you feel about marriage in the next few years and know that you are wanting as loving, lasting and caring family as he had wished. Also assure him (if you havent done so) that you will do anything to secure such a future with him.
It does not sound like he is playing a 'patience game' with you and I know that it is mostly ladies that play that game with men to make sure they are not playing around - happened to me before.
Good luck with your endeavours!!
